Visible crew/equipment: During the closing credits, Frasier is sitting on his couch with a platter of meat beside him. Eddie is sitting up and begging for it and while he is doing this we can see the distinct shadow of his trainer's hand and arm against the couch. The hand goes higher and Eddie waves his paws higher and as the hand goes down, Eddie lowers his paws. Eddie keeps his eye on the trainer during this whole sequence. Once Frasier gives Eddie the platter of meat, the shadow disappears.
Continuity mistake: When Frasier's date calls and cancels, we can see his overcoat covering the back of the couch, but in the next shot, as he says "fat chance", the coat has changed position and we can see several inches of the top of the couch.
Chosen answer: The turkey's stuffing.
